Electrodeposition of Layered Fe/Ni Nanowires in the External Magnetic Field - Morphological and Mössbauer Studies

The presented paper shows a successful attempt to obtain layered Fe/Ni nanowires by electrochemical deposition in the anodized alumina matrix in the presence of an external magnetic field oriented parallel or perpendicular to the plane of the electrodes. In the experiment, various numbers and thicknesses of layers were obtained by sequential deposition. For physicochemical characterization, the obtained nanowires were imaged by scanning electron microscopy, and the amount of Fe or Ni was monitored by energy-dispersive X-ray spectroscopy. The crystal structure of the nanowires was characterized by X-ray diffraction. The magnetic properties of these materials were determined by Mössbauer spectroscopy. Analysis of the obtained data allows us to conclude that the presence of the external magnetic field changes the amount of deposited elements in favor of Fe.
